Exact yet Efficient Graph Parsing, Bi-directional Locality and the Constructivist Hypothesis

ACL 2020 Yajie YeWeiwei Sun

A key problem in processing graph-based meaning representations is graph parsing, i.e. computing all possible derivations of a given graph according to a (competence) grammar. We demonstrate, for the first time, that exact graph parsing can be efficient for large graphs and with large Hyperedge Replacement Grammars (HRGs)... (read more)
